OpenStack Grizzly - Use Quantum2013/09/12 |
|
Create a network to use OpenStack Network Service (Quantum).
This example shows to configure Quantum on the environment below.
|
+------------------+ | +------------------------+
| [ Control Node ] |10.0.0.30 | 10.0.0.31| [ Network Node ] |
| Keystone |------------+------------| DHCP Agent |
| Quantum Server | | | L3 Agent |
+------------------+ | | L2 Agent |
| +------------------------+
|
|10.0.0.51
+--------------------+
| [ Compute Node ] |
| L2 Agent |
+--------------------+
|
| [1] | For example, Configure flat network settings. It's OK to work on any Node if it's installed quantumclient and novaclient. (This example shows to work on ControleNode) |
